Port 2A Channel Noise Floor Level from 3 GHz to 6 GHz
(IF BW = 10 Hz)
1. Press Meas, INPUT PORTS, A, TESTPORT 2.
2. Press Sweep Setup, TRIGGER MENU, SINGLE.
3. When the analyzer finishes the sweep, notice the mean value.
4. Convert the measuredlinear magnitude mean value to logmagnitude
using the following equation:
Power (dBm) = 20 x [log
10
(linear magnitude mean value)]
5. Write this calculated value on the performance test record.
Port 2A Channel Noise Floor Level from 3 GHz to 6 GHz
(IF BW = 3 kHz)
1. Press Avg, IF BW, 3, k/m.
2. Press Sweep Setup, TRIGGER MENU, SINGLE.
3. When the analyzer finishes the sweep, notice the mean value.
4. Convert the measuredlinear magnitude mean value to logmagnitude
using the following equation:
Power (dBm) = 20 x [log
10
(linear magnitude mean value)]
5. Write this calculated value on the performance test record.
In Case of Difficulty
1. Perform the ADC linearity correction constants (Test 52) located in
the standard documentation.
2. Repeat procedure: “6. Test Port Input Noise Floor Level” on
page 1-44.
3. Suspect the A10 Digital IF assembly if the analyzer fails both port
input noise floor tests.
4. Refer to the troubleshooting information in the standard
documentation.
5. Refer to Chapter 3, "Theory of Operation and Troubleshooting‚" for
information regarding specialized troubleshooting for the analyzer.
